AMERICA, NEW YORK. N. Y. A CORPORATIC'N OF PERMANENT END CLOSURE FOR CARTONS.

Specification of Letters Patent.

Patented 11111 23, 3322.

Application filed m 9, 1911. Serial No. 626,023.

Be it known that I, ('i'EORGE W. B itnrr, a citizen of the United States. residing at ifiayonne, in the county of Hudson and State of New Jersey, have invented certain new and u eful .inprovemonts in Permanent .lfilit'i Closures for Cartons; and I do hereby declare the followin to he a full, clear, and

exert description 0 the invention, such as will enable others skilled in the art to which it zippeitains to make and use the same.

'lic present invention relates to vessels of he 1 ,umlly wound type wherein the uniting in or rib is arranged internally, and has its purpose to provide a permanent end eicsure For such vessels which will give a sect ..e and liquid tight joint with the wall of the vessel and with the uniting seam thereof.

To these ends the invention consists in the novci details of construction and combination of parts more fully hereinafter disclos d and particularly pointed out in the cla it e to rri n y:

to the accompanying drawings it i 2, part .f this citication. in w hire nun'urals designate like parts in oil of the viewsI lhguiv 1 vs a, side eieva- [ion at a vessel made in t'oi'uamie with this invention. Fig. 2 is a central vertical section of the vessel showing the internal uniting seam. and the manner oi" applying the permanent end closure. Fig 3 is a top plan view, partly broken away. of the vessel shown in Fig. 1, with the cover removed. a top plan view of the permanent end closure before its application to the vessel and, Fig: 5 is a perspective view of the.

strip, rartiallywound, from which the vessol body is formed.

Referring to the structure in detail the vessel consists of a single strip 1 that'is wound on a mandrel to form a tube and which in the pr cess of making has the side edge. thereof uniiwi to form a locked seam Ti 1 uniting seam onsists of an inset flange having an interned portion 4, on one o ct t strip; 1 ed on the opposite ed e of sad sir-in a flange 5 which is infolded between the flange portions 3 and 4. It from this construction that the uniting seem of the strip provides a liquid tight joint, and leaves the exterior surface ot the well of the vessel substantially flush throughout, thus particularly adapting: th

surface to receive a label or wrapper a ii-ltf out liability of breakin One end of the vesse is provided w t removable closure 6 having the usuu c cumferentially fitting flange 7, as short. n Fig. 2. The permanent end closure or bot. tom of the vessel consists of a disk 8 formed with a flange 9 fitting Within the vessel in close contact. with and longitudinally of the inner surface thereof. The closure cured by having the marginal flange or rim 10 thereof criinped against the nun-g ind edge of the wall of the vessel by a suita ile spinning tool.

To the end that a secure and liquid tight joint be obtained between the closure and vessel. and with the interior spiral seam 2 thereof, the flange 9 of the closure and a like portion of the disk part 8 is formed with a depression'or recess 11, which of the same dimension in cross section as that of the seam 2; and the walls 12 of said recess are disposed diagonally of the flange 9 to accommodate the inclination of said "*"m It results from this construction that dlti diagonally disposed walls I? perform the further function of reinforcing the permanent end closure and in addition the :to provide means for resisting end thrusts on the sustaining surface 8 from within the vessel thereby aflording a maximum resistance from the stock enloyed.

For certain purpose it may be desirable to have a permanent closure at both ends of the vessel, in which event the :rcmovable cover 6 would be replaced by a duplicate of the permanent end closure shown herein.

It is within the purview of the present invention to include the depressed feature 11 which accommodates the inner projecting seam, in any other form of permanent closure. It is also evident that the vessel may be made from either a single strip or from a plurality of stri 9. When it is made of sheet steel the vesse ma be dipped in bath of tin, and thereby furt er close its seam.

What I claim is A cylindrical vessel comprising a spiraliy wounc strip having an internal, uniting seam, and a fixed end closure therefor, comprising a disk having an axiailydepending flange adapted. to fit snugly within said vesup i 96L said (1351; and flange being provided i I 1 i 1 Tn testimony whcrrzuf, I 9153; in sigma" turo, in prcsvnce of two dines GEORGE W.
